Personal amp evolution

Seeing the over night success of the speaker evolution thread, it may be interesting to see what type of amp(s) we have all run. Same deal as the other thread-we will sort of create a puzzle of our systems you'll have to visit multiple threads to put everything together!!! ;)
For me I started:
Adcom GFA-565 monoblocks
Rotel RB-990bx
Jeff Rowland Design Group Model 5
Balanced Audio Technology(BAT) VK-60

either a CAT JL2, BAT VK-75se or Tenor 75Wp on the horizon.
This is my evolution:

Carver “The Receiver 150”
Yamaha RX-V 590
Yamaha RX-V 990
B&K Ref 20 (pre)
ATI 1505
Adcom GFA 5500
McCormack Deluxe 1
McCormack DNA 225
Perreaux E160
EAD TheaterMaster Ovation (upgraded to Ovation 8){pre/pro}
Cinepro 3K6 Mark II
EAD PowerMaster 6300
Cambridge Audio receiver (circa 1973)
Pioneer 626 receiver
Onkyo int amp (25WPC)
Pioneer receiver (100WPC)
Parasound 1200 stereo amp
Parasound 750 stereo amp (2 run as monoblocks)
Bryston 4B ST stereo amp
Bryston 7B ST monoblocks
Krell 400cx stereo amp
1. Panasonic 4 wpc mini-receiver with ic amp section.
2. Pilot 25 wpc integrated solid-state amp
3. Yamaha CR640 40 wpc receiver
4. Nakamichi 630 100 wpc class B solid-state power amp
5. Mitsubishi DA10 100 wpc solid-state power amp
6. Hafler DH200 100 wpc solid-state power amp kits - bought, built, modified, sold several
7. Robertson 4010 60 wpc solid-state power amp

9. Spectral DMA80 100 wpc solid state power amp
10. Music Reference RM-200 100 wpc tube/solid-state hybrid power amp

All served their purpose admirably. The last two were by far my favorites. The last one very much so.
Pioneer SA8100 integrated which I then used the preamp of to drive an used Marantz 1040 power amp. Now have Marantza MA500 power amps. Have also had Pioneer and Technics receivers at various times in the past.h
